.SH NAME
DLAG2S - converts a DOUBLE PRECISION matrix, SA, to a SINGLE PRECISION matrix, A
.SH SYNOPSIS
.TP 19
SUBROUTINE DLAG2S(
M, N, A, LDA, SA, LDSA, INFO )
.TP 19
.ti +4
INTEGER
INFO, LDA, LDSA, M, N
.TP 19

REAL
SA( LDSA, * )
.TP 19
.ti +4
DOUBLE
PRECISION A( LDA, * )
.SH PURPOSE
DLAG2S converts a DOUBLE PRECISION matrix, SA, to a SINGLE
PRECISION matrix, A.
RMAX is the overflow for the SINGLE PRECISION arithmetic
.br
DLAG2S checks that all the entries of A are between -RMAX and
RMAX. If not the convertion is aborted and a flag is raised.
This is an auxiliary routine so there is no argument checking.
.SH ARGUMENTS
.TP 8
M       (input) INTEGER
The number of lines of the matrix A.  M >= 0.
.TP 8
N       (input) INTEGER
The number of columns of the matrix A.  N >= 0.
.TP 8
A       (input) DOUBLE PRECISION array, dimension (LDA,N)
On entry, the M-by-N coefficient matrix A.
.TP 8
LDA     (input) INTEGER
The leading dimension of the array A.  LDA >= max(1,M).
.TP 8
SA      (output) REAL array, dimension (LDSA,N)
On exit, if INFO=0, the M-by-N coefficient matrix SA; if
INFO>0, the content of SA is unspecified.
.TP 8
LDSA    (input) INTEGER
The leading dimension of the array SA.  LDSA >= max(1,M).
.TP 8
INFO    (output) INTEGER
= 0:  successful exit.
.br
= 1:  an entry of the matrix A is greater than the SINGLE
PRECISION overflow threshold, in this case, the content
of SA in exit is unspecified.
